GWR 3700 Class 3440 City of Truro

City of Truro in full steam at Didcot in May 2010, carrying 3717, the number the Great Western Railway gave it in 1912. Built at Swindon Works in 1903 as No. 3440, it is a double-framed 4-4-0 of the City class. On May 9, 1904, the journalist Charles Rous-Marten claimed it reached 102.3 mph descending Wellington Bank in Somerset, which would make it the first locomotive past 100 mph; his timing has been debated ever since, so the record stays a famous argument rather than a settled fact. It belongs to the national collection and no longer runs on the main line.
